A button is a basic component, and an LED is a common light source. But this 16mm LED illuminated pushbutton is a wonderful blend of the two! It's a medium - sized button, large enough for easy pressing without taking up too much space on your project panel. The button comes with a built - in LED that can be controlled independently from the switch action. You can use it for indication or just for aesthetic purposes. The body is made of black plastic with the LED inside. There are two contacts for the button and two for the LED, marked + and - respectively. The forward voltage of the LED is around 2.2V. Just like with any other LED, you should connect a 220 to 1000 ohm resistor in series when using a 3V or higher power supply. This specific button has a green body and LED, and it's momentary and normally open. The two switch contacts are disconnected by default. When you press the button, they connect temporarily until you release it. Since the LED is separate from the button, you have various options to control its lighting, such as making it light up when pressed, when not pressed, or always on.
Using this 16mm green momentary illuminated pushbutton is quite straightforward. First, find a suitable spot on your project panel for the button. It's medium - sized, so it won't take up too much space. When wiring, connect the two button contacts according to your circuit design. For the LED, remember it has a forward voltage of about 2.2V. You need to connect a 220 to 1000 ohm resistor in series with it when using a 3V or higher power supply. You can play around with the LED control to make it light up as you like, whether it's when the button is pressed, not pressed, or always on. As for maintenance, keep the button clean. Avoid getting water or dirt on it as this could affect its performance. If you notice any issues with the button's action or the LED's lighting, check the wiring first to make sure everything is connected properly.
